I say NO to this idea. I want to own my music. I want actual music files on my HDD. You own nothing if you subscribe to Apple Music, all you're paying for is access to the music, but you don't own anything. That's pure profit for Apple and the music artists.
I currently pay for Apple Music, but for me it's to listen to music I like but not enough to own and to hear new music from artists I've never heard before. The artist I REALLY like, I want to own their music so if I do decide to not subscribe, I still have the music.
This is about as much BS as removing the 3.5mm headphone jack.
lest we forget, streaming is also the worst option for artists in terms of compensation.
